Show HN: CLAVIER-36 – A programming environment for generative music
CLAVIER-36 is a programming environment for generative music. Programs are laid out in a two-dimensional grid, and evolve over time according to a fixed set of rules. The system is much like a cellular automaton, in that most of the rules governing the evolution of the system are local.<p>C36 programs describe sequences of discrete events in time. The environment includes a primitive sampler, as a self-contained means of interpreting these events as sound. For full expressivity, though, the system is best used as a generator of data for interpretation by an external musical instrument, such as a synthesizer.<p>The project was very directly inspired by Orca (<a href="https://100r.co/site/orca.html" rel="nofollow">https://100r.co/site/orca.html</a>). It began as my own from-scratch implementation of Orca and diverged over time.<p>It's written in C, and compiled to WASM for the browser.<p>See the following pages for more info:<p>about page: <a href="https://clavier36.com/about" rel="nofollow">https://clavier36.com/about</a><p>user manual: <a href="https://clavier36.com/manual" rel="nofollow">https://clavier36.com/manual</a><p>tutorial video: <a href="https://youtu.be/rIpQmJVMjCA" rel="nofollow">https://youtu.be/rIpQmJVMjCA</a>

Show HN: An MCP Gateway to block the lethal trifecta
Hi there, me and some friends were inspired by Simon Willison's recent post on the "lethal trifecta" (<a href="https://simonwillison.net/2025/Jun/16/the-lethal-trifecta/" rel="nofollow">https://simonwillison.net/2025/Jun/16/the-lethal-trifecta/</a> ) and started building a gateway to defend against it.<p>The idea: instead of connecting an LLM directly to multiple MCP servers, you point them all through a Gateway.<p>The Gateway:<p>- Connects to each MCP server and inspects their tools + requirements<p>- Classifies tools along the "trifecta" axes (private data access, untrusted content, external comms)<p>- When all three conditions are about to align in a single session, the Gateway blocks the last step and tells the LLM to show a warning instead.<p>That way, before anything dangerous can happen, the user is nudged to review the situation in a web dashboard.<p>We'd love for the HN community to try it out: <a href="https://github.com/Edison-Watch/open-edison" rel="nofollow">https://github.com/Edison-Watch/open-edison</a><p>Any feedback very welcome - we'll be around in the thread to answer questions.
Show HN: Aris – a free AI-powered answer engine for kids
I am Andrew, and I’m building Aris (<a href="https://www.aris.chat/" rel="nofollow">https://www.aris.chat/</a>).<p>Aris is a minimalist tool that answers any questions a child has.<p>Encyclopedias, periodicals, field guides, cookbooks, and other print resources we used as kids to find knowledge, learn, and pursue our curiosities have been replaced in most households by something that is not safe for kids: the internet. So instead, kids get Fortnite, Minecraft, and ‘edutainment’ options that don’t compare to the knowledge resources that past generations have had access to.<p>With this in mind, many of the smartest people I know raise (or plan to raise) their kids with access to only a 1990s level of consumer technology, without smartphones, tablets, social media, online gaming, etc. Many of these people believe the last three decades of technological development have been a net negative for kids. When my child was born, I had a similar sentiment. However, there are some major problems with limiting a kid’s access to technology today. To name a couple: 1.) a set of World Book encyclopedias now costs $1,200, and 2.) many print resources aren’t as good as they used to be, if they are even still in print, since the market changed. As parents, we need a safe, simple, nonaddictive way for kids to access and explore the world’s knowledge easily and independently.<p>Aris uses a combination of large language models with policy engines and web search tools to find relevant, timely answers to their questions and only returns the stripped-down answers. It does not return links for them to click on or images or advertisements. Parents can tune the moderation settings as finely as they’d like, preventing discussions about banned topics and even getting as specific as making sure Aris doesn’t tell their second child that Santa isn’t real.<p>The model context handling and system instructions are designed to prevent kids from building emotional reliance or relationships with it. Rather than trying to pull a child into the experience to maximize engagement, Aris is meant to gently redirect the child out of the device into the real world after their question has been answered.<p>We are available as a web app and iPhone/iPad app in the Apple App store, but we have also made our Apple Watch app available in the iOS store as well. We believe minimalist wearables are a good device substitute for younger humans, and we hope Aris can be a healthy addition to those wearables.<p>We plan to make money through premium features that include creating multiple child accounts, accessing premium models for better answers, and for ultra-high usage limits.<p>Come use the app for free on our website or by downloading it in the iOS store by searching for “Aris AI”. We’d love to hear your ideas, experiences, and feedback. Thanks!
